> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.7.1
> Reporter: Rajesh Balamohan
> Assignee: Bikas Saha
> Attachments: DAG_view.png, TEZ-2834.1.patch, TEZ-2834.2.patch,
> application_1442254312093_0095.1.log.gz,

> Will attach the DAG.
> Repro for reference: TPC-DS q_70 @ 30 TB scale.
> "Map 7" completes in 2 waves. Output is very tiny, so reducer 8 gets launched
> slightly late. But before "Reducer 9" can get scheduled, slots are taken up
> by "Map 1", which is not preempted for running "Reducer 9".
> This is with 0.7.1 codebase.
